WASHINGTON ( TheStreet) -- President Obama observed Memorial Day Monday with a call to Americans to honor the sacrifices soldiers have made for their country. Following a wreath-laying ceremony at the Tomb of the Unknowns at Arlington National Cemetery in Virginia, the president said that some Americans are disconnected from those sacrifices. "Today, most Americans are not directly touched by war," the president was quoted saying by The New York Times. "As a consequence, not all Americans may always see or fully grasp the depths of sacrifice, the profound costs that are made in our name." President Obama also reminded American's that "our nation is still at war," in a reference to the war in Afghanistan, the Times reported. The president noted that this year is the 60th anniversary of the end of fighting in Korea, and he offered a "special salute" to veterans of the Korean War, the Times said.
